流浪者：：屠夫"sudo: no tty present and no askpass program specified"试图"cat /etc/chef/client.pem"

Question

Ubuntu 10.04.1 LTS with Vagrant 1.4.3 and Vagrant::Butcher 2.1.5.

我在"vagrant up"结尾得到以下错误:

...
[2014-03-17T22:50:56+00:00] INFO: Chef Run complete in 245.448117502 seconds
[2014-03-17T22:50:56+00:00] INFO: Running report handlers

[Butcher] Failed to create /home/testuser/vagrant_test/.vagrant/butcher/DEV-35-51-client.pem: Vagrant::Errors::VagrantError - The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!
cat /etc/chef/client.pem
Stdout from the command:

Stderr from the command:

Chef客户端运行成功，我们的食谱都安装好了。其中之一是sudo社区食谱，我认为我们忽略了流浪汉用户需要执行cat来读取客户端的条目。pem文件。

谁能告诉我那可能是什么?

更新:

1)流浪用户属于"sudo"组:

$ grep sudo /etc/group
sudo:x:27:vagrant

2) sudoers文件包含一个条目，允许"sudo"组运行任何命令:

# This file is managed by Chef.
# Do NOT modify this file directly.
Defaults      env_reset
Defaults      secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
# User privilege specification
root      ALL=(ALL:ALL) ALL
nagios    ALL=(ALL) NOPASSWD: /usr/local/nagios/libexec/

# Members of the group 'admin' may gain root privileges
%admin ALL=(ALL) ALL
# Allow members of group sudo to execute any command
%sudo     ALL=(ALL:ALL) ALL
#includedir /etc/sudoers.d

Answer 1

这最终不是一个流浪屠夫的问题;那个插件只是碰巧先遇到了这个问题。此外，任何后续的流浪操作也将失败。

Vagrant需要无密码sudo权限。似乎基本盒在/etc/sudoers中声明了它，你用sudo cookbook覆盖了它。

您至少有以下选择:

1. 设置node['authorization']['sudo']['passwordless']属性为true
2. 不要包含sudo食谱的默认食谱。
3. 使用sudo LWRP为流浪用户授予无密码sudo访问权限。
4. 使用或构建一个已经使用/etc/sudoers.d/的基盒

Answer 2

tmatilai很好地解决了这个问题，但是我认为我应该在这里发布我的解决方案以供将来参考。我找到了与他提到的选项#3相同的解决方案，即编写一个添加sudoers的配方。流浪者用户的配置文件。这迫使我修改sudo社区食谱以支持SETENV选项。否则你会得到错误:

sudo: sorry, you are not allowed to preserve the environment

生成的文件是/etc/sudoers.请注意，它需要 NOPASSWD和SETENV:

# This file is managed by Chef.
# Do NOT modify this file directly.
vagrant  ALL=(ALL) NOPASSWD:SETENV: /bin/

以下是我所做的修改:

文件:sudo/菜谱/default.rb

# if the node belongs to the "development" environment, create a config file
# for the vagrant user, e.g. /etc/sudoers.d/vagrant
if node.chef_environment == 'development'
  sudo 'vagrant' do
    user      'vagrant'
    runas     'ALL'  # can run as any user
    host      'ALL'  # from any Host/IP
    nopasswd  true   # prepends the runas_spec with NOPASSWD
    setenv    true   # prepends the runas_spec with SETENV
    commands  ['/bin/']  # let the user run anything in /bin/ without a password
  end
end

文件:sudo/资源/default.rb

# add new attribute "setenv"
attribute :setenv,     :equal_to => [true, false],  :default => false
# include it in the state_attrs list
state_attrs :commands,
            :group,
            :host,
            :nopasswd,
            :setenv,
            :runas,
            :template,
            :user,
            :variables

文件:sudo/供应商/default.rb

# in render_sudoer, add setenv to the variables list
variables     :sudoer => sudoer,
              :host => new_resource.host,
              :runas => new_resource.runas,
              :nopasswd => new_resource.nopasswd,
              :setenv => new_resource.setenv,
              :commands => new_resource.commands,
              :defaults => new_resource.defaults

文件:sudo/模板/违约/sudoer.erb

# generate SETENV option in the config file entry
<% @commands.each do |command| -%>
<%= @sudoer %>  <%= @host %>=(<%= @runas %>) <%= 'NOPASSWD:' if @nopasswd %><%= 'SETENV:' if @setenv %> <%= command %>
<% end -%>
